The "silo" design is prone to tipping, especially when multiple cables are plugged into it. It has some kind of proprietary mount on it, but nothing in the documentation (or even a template) about it.
The dual-band "N" (not AC) model I tested was loaded with features though, including all kinds of access control, Radius authentication, Guest networking, etc. It also has a USB port, although it's 2.0 and not as straightforward to set up and then use as other devices I've used.
